Dorothy Hodgkin - a Life in Science

A Catalyst article about Dorothy Hodgkin who was a pioneering scientist, a peace activist, a mother of three and a Nobel Prize winner. The article looks at her life and work in science. She did valuable work as an X-ray crystallographer and in finding the structure of biologically important molecules such as...

Fishing for Clues

This Catalyst article describes how fish can help scientists to learn more about human biology. Understanding how human bodies work and what causes human disease is the key to future medical breakthroughs. Most discoveries in medical science are a result of experiments that cannot be performed on humans. Animal...

Hooke's Law of Springs

This Catalyst article looks at the work of Robert Hooke, an employee of the Royal Society, Britain's oldest scientific society. His job was to present two or three different experiments each week to the assembled members of the society – and this was at a time when experimentation was new and there were no books of...

Blocking Viruses with Synthetic Receptors

This Catalyst article explains how chemists build molecular 'traps' to mimic the surface of a cell. To scientists, sugar is much more than a food; sugar molecules can also form polymers which act as ‘molecular bar codes’ to help cells recognise each other. The article describes how chemists made a synthetic...
